Non-standard reinforcement
Non-standard reinforcement options :
• Duct fabrication using the dual or multiple duct design
• Angle profiles or reinforcing channels mechanically fixed inside/outside ductwork
• Single duct design reinforced with “Bent” reinforcing bars that suit the shape of
the ductwork.
Where the standard reinforcing bars cannot be installed:
• top of a large square elbow
• where a large branch takes off from a large duct
• large end cap.

Reinforcement – End Caps
• Reinforcement required whenever the schedule of reinforcement for straight duct of the

• Reference is the SMALLEST size of the end cap. E.g. end cap size 56” x 40”: check the
schedule of duct reinforcement for 40”
• Specifically designed reinforcement, e.g. channel profiles 1
